Constructor & Destructor Documentation

simthlib::WssusChannelDelayProfile::WssusChannelDelayProfile (  int  id, simth::DeviceSystemIntf *  s, const simth::PropertyList &  pl, double  max_doppler, std::auto_ptr< DelayProfile >  profile )

Constructor that takes an auto_ptr to a delay profile. This means, that this class takes the ownership of that delay profile. Parameters: id  The Device ID s  The pointer to the simulation system pl  The list of properties this device has max_doppler  Maximal doppler frequency in seconds. profile  Pointer to a delay profile.

Member Function Documentation

virtual double simthlib::WssusChannelDelayProfile::diceNewDelay (   )  const [protected, virtual]

Returns a (pseudo) random delay value with the specified exponential probability profile. Implements simthlib::WssusChannel.

virtual double simthlib::WssusChannelDelayProfile::maxDelay (   )  const [protected, virtual]

Returns the maximal signal delay that cam be returned by diceNewDelay(). Implements simthlib::WssusChannel.

virtual void simthlib::WssusChannelDelayProfile::print (  std::ostream &  os  )  const [virtual]

Reimplemented from simthlib::WssusChannelJakesUniform.

void simthlib::WssusChannelDelayProfile::resetDelayProfile (  std::auto_ptr< DelayProfile >  newProfile  )  [protected]

Resets the delay profile. Since the argument type is an auto_ptr this class will take the ownership.

These are the properties of class WssusChannelDelayProfile . This list is auto-generated from the XML-Devicelist of this device by means of an XSLT transformation script. Description of this device in the XML file: WSSUS channel with a delay profile given by derived classes. Note that this class also has the Properties of its base classes. The direct base class is simthlib::WssusChannelJakesUniform ; direct link to its propertylist should be propertylist_WssusChannelJakesUniform(). The list below usually includes the properties that have been inherited from the base classes; the properties which belong only to this class can be found at the end of this list. input_length <sequencelength>, default "-1" -- The length of the input sequence. '-1' means it will be determined dynamically at runtime. snr <string>, default "" -- Name of the SNR loop variable in your simulation setup channel_refresh <string>, default "" -- Name of the channel refresh loop variable in your simulation setup 3 properties in this class. The above properties have been inherited from the base class simthlib::Channel . num_path <unsigned>, default "30" -- Important WSSUS parameter: The number of scattering paths in the WSSUS channel model. This number should be at least 30 or larger in order to model a sufficiently random channel. normalization_mode <enum>, default "standard" -- The normalization mode in this channel: standard, time, or freq. Additionally the channel will be normalized by the number of transmit antennas. freq_dist <double>, default "312500" -- Only for normalization mode 'frequency': Distance of frequence samples when calculating the normalization factor in frequency normalization mode num_freqs <unsigned>, default "64" -- Only for normalization mode 'frequency': Number of frequency points/samples when calculating the normalization factor in frequency normalization mode rice_factor_db <double>, default "-1e6" -- The rice factor of this channel in dB. If unset (minus infinity), then there is no line of sight. The dB property overrides the scalar one. rice_factor <double>, default "0.0" -- The rice factor of this channel as a scalar. If unset (zero), then there is no line of sight. 6 properties in this class. The above properties have been inherited from the base class simthlib::WssusChannel . max_doppler <double>, default "" -- Maximum doppler frequency in Hz. This is f_0*v/c_0, i.e. for IEEE802.11a or Hiperlan/2 this means: 1 km/h = 5 Hz 1 properties in this class. The above properties have been inherited from the base class simthlib::WssusChannelJakesUniform . No properties defined in this particular class.
